Fix compatibility issues with Qt/PyQt6 versions

- Add null check for message.message in search filter
- Handle missing colorScheme/colorSchemeChanged methods for older Qt versions
- Add display check to prevent hanging in headless environments
- Update build documentation with system package alternative
- Update PyInstaller spec for Python 3.12
- Improve run.sh script with venv management

+**Alternative: System packages (Debian/Ubuntu)**

+If you prefer to use system packages instead of pip, install the required PyQt6 packages:

+$ apt install python3-pyqt6 python3-pyqt6.qtwebsockets python3-pyqt6.qtmultimedia
